NOTES ON OPERATION:
Master Modes: There are 5 different master modes which can be enabled:
1. Manual Mode. In this mode, the FirePlug makes connections when a Connect
Command “C”, is received. This command can also contain the Bluetooth address of
the remote device. If no device is specified, then the store remote address is used.
The connection can be broken if the special break character or string is sent (use the SO
command to set the break character) This is a low speed connect mode.
2. Trigger Mode. In this mode, the FirePlug makes connections automatically when a
character is received on the serial port. The connection will continue as long as
characters are received on either end. There is a configurable timeout (which is set
using the ST command) which will cause a disconnect after XX (from 1 to 254) seconds
of inactivity. This is a low speed connect mode.
3. Auto Mode, 4 DTR, 5 ANY modes. In these modes, the FirePlug makes connections
automatically on powerup, and re-connects when connection is lost. This is the high
speed connect mode, and cannot be broken by software break characters. In DTR and
ANY modes it can be broken by setting the DTR line inactive.
Low Speed Connect Mode NOTE: in Manual and Trigger mode, the Blueport is
making a LOW speed connection, that is, data is being processed by the Blueport before
being sent over the air. Because the Blueport is looking for break or config
character(s), the latency will increase and data rate will be decreased in these modes.
Thus it is recommended that for data rates above 57.6K these modes not be used.
Configuration Timer Settings
Security Issues, Pin Codes and Link Keys: If A> Blueport, or B> the remote device
has authentication enabled, the following process occurs: The first time a connection is
made, a “passkey” is used. This is a series of numbers or characters, “1234” is the
default for the Blueport. Once this is entered, the remote Bluetooth device and the
Blueport compare their passkeys and if they match, a link key is generated, which is
stored by the Blueport. Upon subsequent connections, the devices will first compare link
keys and if they match no pin code will have to be re-entered. If the remote device is a
PC or PDA, a prompt is generally made to the user to enter this pincode. To remove the
stored link key on the remote device, generally you “unpair” with the Blueport. To
remove the link key on the Blueport, you can change the Pin Code. This will remove
any previously stored link keys from the blueport, forcing a new Pin Code exchange
process to occur upon subsequent connection attempts.

Wake PC on Bluetooth Connection Feature: Another useful feature of the FirePlug is
the ability to wake a suspended/sleeping PC or Apple MAC. If a PC or MAC is in
suspend/sleep mode, a remote device connecting into the FirePlug will cause the PC or
MAC to wake from suspend.
